Adorable chinnies. Thanks for sharing.
I don't know many people who keep the sort of wheel in their cage that you have in your picture, it's been said they are dangerous. Have you ever had any problems with that kind? Logically I can understand the arguement against them but I guess you would be a good person to ask if you ever have chin wheel accidents with that sort of wheel. This can get to be a pretty heated issue and I don't intend it to be one, I am truly curious how often or if you have had issues with that kind of wheel. Or maybe it was a chin wheel urban legend.
I use flying saucers but mostly because that's all I know about and my chins like them and I've never had any accidents with them. I swear they like to poop on them and fling it across the room, having poop flinging contests and a flying saucer wheel, as a chin you can get your poop flung pretty far.
